Cisco QSFP-100G-SR4-S Compatible 100GBASE-SR4 QSFP28 850nm 100m Optical Transceiver Module

I found this website through Google search. Their website is well made and the product prices are also very good, so I chose to buy some 100G SR4 here. The courier delivered the product on the fourth day of placing the order, which was very fast. The product was well packaged and the performance was excellent. It was plug and play. A very good shopping experience. I think I will choose them next time.

Used this 100GBASE-SR4 to build breakout connectivity and also bought MTP cables from QSFPTEK, great one stop shopping experience!

The performance of this 100G qsfp28 module is perfect, it is seamless to our switches and the latency of these modules is very low, no difference compared to the brand optical module.

Purchased 10 pieces of 100G SR4 optical modules, and some MMF fiber, price is always the deciding factor for us as a small company, so we asked customer service if we could get a discount on a large order, and Wendy gave me the answer that we could, and comparing to other vendors, QSFPTEK offered us the best price!

Very good price! Our company is on a very limited budget and we also purchased matching fiber from QSFPTEK, again at a very CHEAP price!

I bought this module to test the 1:4 application on my Cisco switch and used it with the original Cisco module. During the test, first of all, there was no compatibility problem, and the connection was very good. And its speed was the same as it was described. I have to say that this is a great module.

Bought some 100G SR4 to upgrade my network, it works great, stable data transfer, and fully compatible with my 25G devices. The price is absolutely great, and the delivery service is very fast!

This module came at a highly competitive price point and performed flawlessly, meeting all expectations. I was particularly impressed that it seamlessly paired with MTP female 12 Fibers Type B OM4 trunk cable, making integration a breeze.

QSFPTEK manufactures excellent optical modules, and their customer service is exceptional. The technicians are highly knowledgeable and readily assist with any networking inquiries. The 100GBASE-SR4 module has performed reliably on my switch for the past two years.

These optical modules are an excellent choice for anyone looking for a cost-effective and reliable networking solution. They provide high-speed connectivity and the ability to upgrade to 100G in the future.
